Dear SBN Bank,
It is to inform you that you have accidentally deducted an amount of INR 600 from my bank account for not maintaining the minimum required balance. However, I already had shared the concern as well as received the approval for the same.
I request you to look into the matter and do the necessary amendments as soon as possible.
Expecting cooperation for credit.
Subject: Wrong amount deducted.
Dear YBN Bank,
I have just received my monthly statement for my checking account and debit card, and I found that I was charged INR 1200 for a one-day overdraft that amounted to INR 500. Instantly after I received notification of the overdraft, I applied for and get approval for line of credit on such a situation.
So, I was assured that any charges for the overdraft would be reimbursed.
Thank you for your assistance.
